Answer:
Step-by-step explanation:
The race is 111.6 m long.
8 hurdles spaced 12.3 m apart means 7 spaces that are 12.3 m in length; 7*12.3 = 86.1
Add to this the distance to the first hurdle and the distance from the last hurdle:
86.1+15+10.5 = 111.6 m
The set of integers is not closed under the operation of division because when an integer is divided by another, the results are not limited to only integers i.e. zero and decimals are possibilities
<h3>How to determine the true statement?</h3>
Integers are numbers without decimal points
When integers are divided, the possible results are:
The decimal and the zero possibilities imply that the set of integers is not closed under the operation of division
This is so because when an integer is divided by another, the results are not limited to only integers i.e. zero and decimals are possibilities

Answer:
Step-by-step explanation:
7+4y=7-5y+54
Collecting like terms
4y + 5y = 7 - 7 + 54
9y = 54
y = 54/9
y = 6
